FLOORPWASHIN G MACHINE.

Application filed April 30,

To all whom it may concern:

Be it known that I, PIOTR Genny, a citizen of Russia,.residing at East Chicago, in the county of Lake and State of Indiana, have invented certain new and useful Improvements in Floor-Washing Machines, of which the following is a specification.

The primary object of the inventionis theprovisionof adevice adapted for easily and quickly cleaning large areas of floor space by a washing and scrubbing operation.

A further object of the invention is to provide a device arranged for simultaneously pumping a washing fluid during the propulsion of a scrubbing means over a surface to be cleaned,-the device being readily operated by a single attendant and possessing great strength and utility.

A still further. object of the invention is the provision of a floor scrubber adapted for propulsion over a surface to be cleaned provision being made for supplying washing fluid under suitable pressure to the scrubber I while the device is in motion.

In the drawings forming a part of this application and in which like reference characters refer to corresponding parts throughout the several views,

Figure 1 is a side elevation of the device partially broken away,

Fig. 2 is a top plan view thereof,

Fig. 3 is a vertical central sectional view through a portion of the pump structure emloyed and taken on line III-III of i 1 Fig. 4.- is a similar sectional view through the pump and the adjacent portion of the fluid reservoir and Fig. 5 is an enlarged sectional detail view of the operating means for the device taken upon line V-V of Fig. 1.

My invention is adapted for washing and scrubbing extended surfaces such as floors and provides a platform 10 mounted upon rear wheels 11 and a scrubbing brush 12. The said brush 12 constantly rests upon the surface to be scrubbed such as the floor 13 and is provided with operating gears 14 carrled by a shaft 15 adapted to be turned by means of a crank shaft 16 through pinion connections 17. A power shaft .18 is journaled through a rearwardly positioned upwardly extending handle 19 operatively connected by means of pinions 20 with the crank shaft 16. A casing 21 is positioned at the upper free end of the handle 19 provided Specification of Letters Patent.

Patented Nov. 9, 1920. 1918. Serial No. 231,648.

. with an operating crank 22 at the side thereof connected by means of pinions 23 with the powershaft 18. y

A V-shaped brace 24 connects the handle 19 with a tank 25 mounted upon the platform 10 by means of legs 26 and adapted to contain a supply of washing fluid 27. A handhold 28-is positioned upon the casing '21 and it will be seen that the hand-hold 28 may be readily grasped by one hand while the crank 22 may be turned by the other hand for revolving the power shaft 18, crank shaft 16 and the transverse shaft 15 for turning the brush 12 and moving the entire device either forwardly or rearwardly over the floor 13.

A suitable means is provided for supplying the brush 12 with the fluid 27 under pressure consisting of a tubular pump 29 operatively connected to the crank shaft 16. The pump 29 communicates with the tank 25 by means of the angularly bent lower end 30 of the said pump while a controlling valve 31 i positioned in said pump end. A piston 32 is slidably arranged within the pump 29 having the usual form of flap valve 33 and also having an operating rod 34 extending upwardly through a stuffing box or cap 35 at the top of the pump.

A flattened hollow post 86 is mounted upon the platform 10 flaring downwardly and having openings 37 in the front and rear walls thereof adapted for the accommodation of the crank portion 38 of the shaft 16. Journaling posts 39 are provided for the shaft. 16 upon the platform 10 adjacent theopposite sides of the post 36. During the turning of the crank 22 for revolving the brush 12 and causing the device to travel upon the floor 13, the crank 38 revolves within the bottom portion of the post 36 and being operatively connected to the pump rod 34 by means of a pitman 40 and a link 41, the piston 32 will be continuously operated for pumping the fluid 27 during the entire travel of the device.

The link 41 slidably extends through opposite slots 42 in the sides of the post 36 acting as guides for the upper end of the pitman 40 while the downward flaring of the said post accommodates the pitman for V movement therein during the revolving of the crank 38. A hood or discharge nozzle 43 is mounted centrally over the brush 12 by means of the discharge pipe or spout 44; of the pump 29, the saidspout passing nozzle 43 upon the brush 12land whereby the brush is enabled to clean the floor 13 during the travel of the device thereover by means of the power s -lied by the attendant to the turn crank 22. What I claim as new is In affloor washing machine, a platform mou'nted upon rear supporting wheels and a forward transversely arranged rotary scrubbing brush, a crank shaft journaled 'upon the platform longitudinally of the latter andrearwardly of said brush, a handle rigid with and extending upwardly from the-rear of said platform, means operatively geared to the rear end of said shaft for rotating the latter, a second shaft journaled transversely of and on the platform'rearwardly of said brush and rotatably geared to the forward end of said crank shaft, drlvmg connections between sald transverse shaft and the opposite ends of said brush,

and means including a pump operatively connected to the crank of said crank shaft for supplying a washing fluid to said brush.

In testimony whereof I affix my signature. V
